These covers pair lustrous lining fabric (sold by the yard) with wool or other matte yardage. For a colorful seam, the lining's selvage edge is on display.
Martha Stewart Living, March 2010
Using disappearing-ink pen to mark measurements, cut two 13-inch squares from menswear fabric.
From lining fabric, cut a 13-inch-long rectangle, with the desired width, so that the selvage edge runs along 1 long side.
Lay lining-fabric rectangle on 1 square, right sides up, so the long, nonselvage edge of rectangle aligns with edge of square.
Lay second square on top, right side down. Pin fabric pieces together. Stitch around perimeter with a 1/2-inch seam allowance, leaving a 10-inch opening on 1 side. Turn pillowcase right side out. Press pillowcase flat around the edges.
Insert pillow insert; slip-stitch to close opening.
